cmEthernetNetPortSfpLinkLength
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortSfpLinkLength
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.7.1.124
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This object provides the SFP Link Length. This is applicable only when cmEthernetTrafficPortMediaType is fiber or coppersfp.
What is cmEthernetNetPortSfpLinkLength?
This read-only Integer32 reports the SFP transceiver's rated link length, applicable only when the port's media type is fiber or coppersfp. It serves the same fiber-planning purpose as cmEthernetNetPortSfpReach, letting an admin confirm the installed optic's rated distance capability against the actual physical span before turning up a circuit. For example, on a long-haul metro fiber run, an admin would check cmEthernetNetPortSfpLinkLength to confirm the transceiver is rated for a distance at least as long as the actual fiber path before trusting the link's signal margin.
